The instrument was designed as not only high speed and high accuracy measurements but also performs superior optical resolution for 400 nm stage, which important in rare-earth metal, with an energy saving design concept. The newly developed Hyper Direct Drive and superior control technology enables high precision measuring. Features 1. Hyper Direct Drive System The hyper direct drive improves the rotation speed of the diffraction grating 10 times that of conventional systems. It is able to drive the full spectrum area within one second. Measurement time reduced and sample consumption is minimized. High precision measurements are possible by the excellent positioning precision of the direct drive motor and intelligent control sequence. 2. High speed scan measurement Hyper Direct Drive can scan all wavelength region within one second. As a result, time of conditions setting for performing wavelength selection of qualitative and quantitative analysis is markedly faster. With the improved algorithm, all elements qualitative analysis can be performed within one minute, which is one fourth of conventional methods. 3. WRS(Wide Range Scan) Hyper Direct Drive can scan the wavelength by minimum 2 pm steps. A function was added that acquires a detailed wide spectrum freely. Qualitative judgment and wavelength selection for quantitative measurement, etc. can be performed based on this information.
